68 described species of cryptic subterranean ants from the Old World tropics and warm temperate regions are studied. The phylogeny is inferred from ultra-conserved elements (UCEs) using maximum-likelihood, enabling the first published description of male ants in the Anomalomyrmini tribe. This dataset, associated with research from the University of California, Davis, provides a male-based diagnosis and dichotomous key for the subfamily.
Version 1.0, dated 2023/03/24, contains extracted cross-section data points and Monte Carlo predictions for muon neutrino charged-current interactions on hydrocarbon without pions. The data release includes covariance matrices, flux histograms, and analysis binning information from the T2K experiment, provided by Andrew Cudd of the University of Colorado Boulder. Supporting files include ROOT and CSV formats, along with example scripts for chi-square calculation.
924 genealogical files form a database of marriages in the Netherlands from 1600 to 1999. The anonymized dataset includes lifespans, marriage ages, and urban/rural classifications for birth, marriage, and death locations. It was constructed by Utrecht University researcher Corry Gellatly from user-contributed family trees.
Marriages conducted in the Netherlands between 1600 and 1999, with anonymized records for spouses, their parents, and children. The dataset is derived from 924 genealogical files contributed by users of genealogieonline.nl, error-checked and combined into the GO 924 set. It includes lifespans, marriage ages, and location data for births, marriages, and deaths.
GO924 is a dataset of marriages conducted in the Netherlands between 1600 and 1999, derived from a genealogical database. It includes anonymized information on spouses' lifespans, marriage ages, and birth, marriage, and death locations, with urban/rural classification for events before 1800. The data was compiled by Corry Gellatly of Utrecht University from over 924 contributed family tree files after error-checking.
Generalized Anxiety Disorder data from the Project on Human Development in Chicago Neighborhoods (PHDCN) Longitudinal Cohort Study. The study followed over 6,000 randomly selected children, adolescents, and young adults to examine influences on antisocial behavior. This subject-level instrument, adapted from the Diagnostic Interview Schedule for Children (DISC 4), was administered to Cohorts 9, 12, and 15 during Wave 2 (1997-2000) and obtained information regarding subjects' worrying and anxiety.
A research dataset from Stanford University provides a bird's eye view of the mouse enteric nervous system (ENS). It describes the regional cytoarchitecture and variation, including the organization of neurons into circumferential stripes that form during the perinatal period. The data highlights differences in stripe width and neuronal subtype distribution between the small intestine and colon.
BLASTNet 2.0 provides 744 full-domain samples across 34 configurations, totaling 2.2 TB of reacting and non-reacting flow physics simulation data. The dataset was developed to foster open and fair machine learning development within the fluid dynamics community. It is designed for scientific engineering tasks in automotive, propulsion, energy, and environmental applications.
Roughly 90 percent of world trade in cotton-spinning machines is documented in this dataset of orders from British textile machinery firms. It covers virtually every major national cotton industry except the United States, providing detailed machine specifications like frame size, speed, yarn count, and raw cotton types. The data was compiled for a long-term study on the divergent global adoption of mule versus ring spinning technologies.
Monthly average dissolved carbon dioxide concentrations for China's Lake Taihu were estimated from MODIS satellite data from July 2002 to December 2018. The dataset, created by Tianci Qi of the Chinese Academy of Sciences, has a reported coefficient of determination (R²) of 0.84 against field observations. It reveals a significant declining trend of 0.80 μmol L⁻¹ per year and distinct seasonal and spatial patterns in CO₂ levels.
Lake Taihu's monthly average dissolved carbon dioxide concentrations from July 2002 to December 2018, estimated using MODIS satellite data. The dataset was created by Tianci Qi of the Chinese Academy of Sciences and has a reported coefficient of determination (R²) of 0.84 against field observations. It reveals significant seasonal dynamics and a declining annual trend of 0.80 μmol L⁻¹ per year.
March 26, 2026 briefing package prepared for a hearing before the Standing Senate Committee on Energy, the Environment and Natural Resources. The document likely contains prepared statements, reports, and progress updates on environmental assessments and policy. It was authored by the Office of the Auditor General of Canada and published on the open_canada platform.
Quarterly price and cost indices serve as a basic tool for estimating, cost checking, and fee negotiation on public sector construction works, including roads. The dataset is designated as National Statistics and was produced by the Department for Business, Energy and Industrial Strategy, with responsibility transferring to the Office for National Statistics in April 2015. It is available in HTML format under the OGL-UK-3.0 license.
Gross Value Added (GVA) data measures the value generated in the production of goods and services for Lincolnshire. The dataset provides annual figures in billions of pounds, pounds per head, and as a percentage of the UK equivalent, published by Lincolnshire County Council and sourced from the Office for National Statistics. Data is updated annually, with the most recent year's figures normally provisional.
Two-part geodetic product from Cooperation OGD Österreich and Wikimedia Österreich enables one-step transformation of ellipsoidal heights to physical heights. The data is suitable for adjusting heights from laser scanning and GNSS measurements to conform with Austrian map systems. It is available in CSV and GEOTIFF formats under a CC-BY-4.0 license.
149 mappable criteria were tested to create a national-scale mineral potential model for Iron Oxide Copper-Gold (IOCG) deposits in Australia. The model successfully predicts 91.7% of known deposits within 8.3% of the area, highlighting new prospective regions. The study was published in Ore Geology Reviews in 2025 and the data is hosted by Geoscience Australia.
40.75 MtCO2e of greenhouse gas emissions were estimated for London in 2012, representing a 10% reduction from 1990 levels. The Greater London Authority produces this annual inventory to measure progress against the Mayor's Climate Change Mitigation and Energy Strategy. It estimates energy consumption and CO2 emissions from Homes, Workplaces, and Transport within Greater London.
Three sediment cores from Nara Inlet in the Whitsunday Islands provide data on sediment accumulation over the last 3000 years. The cores contain a mix of terrigenous clay and shallow marine carbonate, with the carbonate component averaging 25.80% by weight. This dataset, sourced from the Australian Ocean Data Network, characterizes a tropical mixed clastic/carbonate system on the middle shelf of the central Great Barrier Reef platform.
The Aqua satellite's MODIS sensor provides multi-spectral measurements of sunlight reflected from the ocean surface layer. These data use the OC3 algorithm to infer chlorophyll-a concentration, a proxy for phytoplankton biomass. Production of contemporary MODIS data ceased on 2024-12-26, with users directed to VIIRS instruments for newer data.
Australian Ocean Data Network provides satellite-derived chlorophyll-a concentration data. The data is inferred from multi-spectral measurements by the VIIRS sensor on the NOAA20 platform using the Garver-Siegel-Maritorena (GSM) algorithm. The dataset was last updated on 2026-07-13.
